Benefos 1680 is a phosphite type antioxidant of low volatility and extremely resistant to
hydrolysis. This secondary antioxidant provides excellent heat stability and antioxidation,
with good compatibility with resins and excellent extraction resistance. Benefos 1680
performs best when combined with a primary antioxidant.
Benefos 1680 is a phosphite type antioxidant of low volatility and extremely high resistance to hydrolysis.
It provides excellent antioxidant process stability to organic polymers, resistance to discoloration and adds long-term protection against thermo-oxidative degradation after processing.
Benefos 1680 is a secondary type antioxidant.
It is particularly useful in polyolefins and olefin-copolymers such as polyethylene, polypropylene, polybutene, and ethylene vinyl acetate copolymers as well as polycarbonate and polyamides. Other applications include use in linear polyesters, high impact polystyrene, ABS, SAN, adhesives, natural and synthetic tackifier resins, elastomers such as BR, IR, and other organic substrates. |
